SPEGIFICATION formingpart of Letters Patent No. 712,404, dated October 28, 1902.

Application filed a... 16, 1902.

To all whmn. it ma t concerns 1 Be it known that I, EDWARD JOHN ONEILL,

of Ada, in the county of Hardin and State of Ohio, have invented a new and useful Im-" proveinent in Railroad-Crossings, of which the following isa specification.

My inveiition is an improvement in railroadcrossings, having for an object, among others, to provide a simple construction whereby there is furnished a continuous track in one or the other direction of the crossing by means of swinging rail-sections and by which the swinging rail-sections are locked in their different adjustments; and the invention consists in certain novel constructions and com binations of parts, as will be hereinafter described and claimed. i

In the drawings, Figure l is a top plan view of a crossingembodying my invention. Fig.

2 is a detail top planview of the turn-table for the swinging rail-section. Fig. 3 is an end view of such rail-section in place in its turn-table. Fig. 4 is a top plan View. Fig. 5 an edge View, andFigzfi is a sectional View, of the seat-plate for the turn-table. Fig. 7 illustrates in detail one of the pivot-stands for the horizontally-rocking lever. Fig. 8 illustrates in detail one'of the guides for the slide-rods. Fig. 9 illustrates in detail one of the pitmen connected with the cam-frames.

Figs. 10, 11, and 12i1lustrate in side View, re: spectively, the operating-cam. Fig. 13 illustrates the pivot-shaft for such cams. is a top plan view, and Fig. 15 a sectional view, of the seat-plate for the fixed sections, and Figs. 16 and 17 illustrate in detail the sliding lock. Fig. 18. is a sectional View on about line 18 18, Fig. 12; and Fig. 19 is a detail cross-section on about line 19 19 of Fig. 1.

By my invention I seek to dispense with the breaks in the rails which occur at arailroadcrossing, such as are now commonly in use,

and thus avoid the blowsof the wheels, which result in much damage not onlyto the rails and wheels, but to other portions of the cars,

and by avoiding this I also avoid the noise resulting fromthe pounding of the rails, dispense with the necessity of constantly tamp ing beneath the crossing, especially in the Wet season,and relieve the passengers of the jolting resultingfrom the pounding as now commonly experienced.

other, the rails A of the track leading from right to left, crossing at a right angle the line of the rails B, as shown. The pair of tracks crossing each other have the fixed rail-sections terminating on opposite sides of the 1 point of crossing, and swinging rail-sections O are pivoted centrally between their ends within the center of the space between the ing rail-sections can be turned into alinement with the rails A or the rails B. The fixed rail-sections have their ends adjacent to the crossing curved on concave lines 1, while the ends of the swinging rail-sections C have their ends curved on convex lines 2,. so they will fit and conform to the concave ends 1 when turned into alinement therewith, as shown in Fig. 1.

I will first describe in detail the construcadjoining endsof the fixed rails, so the swing- As shown in Fig. 1, the 'tracks cross each.

. tion at the crossing of one rail by another, as

all the crossings are alike, and will then describe the means for shifting the swinging rail-sections and for swinging the locking devices. 7

At its end adjacentto the:crossing each fixed rail-section is seated on a chair-plateD, having a wing D to overlie the base of the frail and provided in its end away from the crossing with a dovetail groove D to receive the rib E on the sliding lock-plate E, presently described. The flange D not only overlies and braces the fixed section, but also forms astop for the swinging rail-"section when adjusted into alinement with the fixed .rail- 1 section. The locking-plate E is held by bolts E slidably to the fixed rail-section and is movable longitudinally along, the chair-plate D, with its rib E operating in the groove D toposition where it will overlap the end of theswinging rail-sectionwhen such swinging rail-section is in a line with the fixed rail or ing rail-section, as may be desired. This sliding lock-plate is operated by the means pres- 1 ently described;

} back away from the crossing to clear the swing- The swinging rail-section O is held ina' clamp F on the upper side of the turn-table F, which turn-table has its base F circularand tapered, as shown in Fig. 3, and is provided on itsunder side with a central stud F as shown in Fig. 3. The turn-table base Gis composed of two sections G, combining to provide-the circular undercut seat G for the tapered base F of the turn-table F and the circular socket G for the pivot-stud F the turn-table F fitting and turning within the base G in the operation of the device, as presently described.

For swinging the rail-sections C from one position to the other I employ longitudinallymovable slide-rods H, which are connected by pitmen H with the turn-tables and when moved in one direction swing the rails of such turn-tables into alinement with the rails A vand when moved inthe opposite direction swing the rails G into alinement with the rails B. These slide-rods H are shown as extending parallel with the rails A'and are connected at one end with cranks I on the shaft I, which is also provided with a crank 1 which is connected by a pitman I with an operating camfralne Y, as shown in Fig. l. Alongside the same frame Y are arranged and operate camframes X and Z. The cam-frames X and Z operate the sliding lock-plates. To this end -I provide a pitman J, connecting the camframe Z with the crank K on a shaft K, which shaft is also provided with a crank K, connected by pitman K with a slide-rod L. This slide-rod L operates bell-crank levers M, which in turn operate slide-rods N, which extend parallel with the rails B and are connected by levers O and P with the lockplates operating upon the fixed sections of the rails B. The levers O engage at one end with their respective lock-plates and at their other ends directly with the slide-rods N. The levers P connect at one end with their sliding lock-plates and at their other ends with short slide-rods P, whose other ends connect by levers P with the slide-rod N, this construction operating to cause the locking-plates of the rail-sections B on opposite sides of any crossing to be moved toward or from each other,according to the direction of movement of the slide-rod N. The camframe X is connected by a pitman J with a crank Q on a shaft Q, such shaft being also providedwith cranks Q connected by pitmen Q with slide-rods R, which are connected by means of levers and slide-rods S, T, T, and T corresponding to levers O P, slide-rod P, and lever P before described, with their respective sliding lockplates,so the movement of the slide-rods R will operate the sliding lock-plates operating in connection with the rail-sections A, as will be understoodfromtheforegoingdescription. Guides 3, as shown in Fig. 8, are provided for the several sliderods, and pivot stands 4, as

shown in Fig. 7, are supplied for the rocking levers. The cam-frames are fixed on a shaft U, so they will turn therewith, and are spaced apart by means of collars U on such shaft, and the shaft is provided with a lever U, so the shaft may be turned to swing the camframes to different positions. Each camframe has a portion or portions curved on an stood from Figs. 1O, 11, and 12. cam-frame X has portions X and X formed arc struck from its center and an eccentric or cam'portion or portions, as will be under- Thus the on circular lines, and a portion X which operates as a cam to push or pull the pitman J, and thus turn the shaft Q in one directionor the other. The cam-frame Y has circular portions Y and Y and an eccentric or cam portion Y while the cam-frameZhas curved portions Z and Z and a short cam portion Z It will be noticed that throughout the several cam-frames the cani portion is intermediate the curved portions and the several frames moving together will operate their respective slide-rods to secure the desired result. .Thus if the parts he as shown in full lines,-Fig. 1, the cam-frame Y will have operated the rail-sectionsO into alinement with the rails A and the cam-frame X will have operated its sliding lock-plates E on the rails A into engagement with the rail-sections O to lock the same firmly in position. If now it is desired to adjust the swinging rail-sections 0 into line with the rail B, the lever U may be swung over, operating first to free the lock-plates E of the rail-sections A from engagement with the rails C, after which the cam-frame Y will turn the'rails G into alinement with the rails B, and after that the cam fran1e Z Will operate through the connections before described to adjust the sliding lock-plates of the rail-sections B into engagement with the rails O to lock the latter into alinement with the rails B. The construction is simple and operates effectively for the desired purpose.

While the rails A and'B are shown crossing each other at a right angle, it will be understood they may be arranged at a different angle without departing from the principles of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. The combination substantially as herein described of a pair of tracks crossing each other and having the main rails terminating on the opposite sides of the point of crossing, rail-sections swinging within the crossings into alinement with the fixed or main rails of the different tracks, slide-rods, pitmen con: necting the slide-rods with the swinging railsections whereby to swing the latter, lockingplates movable along the fixed rail-sections into and out of engagement with the swinging rail-sections, the main slide-rod for operating the locking-plates of the rails of one track, the slide-rod parallel with said first slide-rod, and the cross-rods connected with and operated by the latter slide-rod for opererating the locking-plates of the rails of the other track, and means for operating the main slide-rods substantially as set forth.
